The A/C refrigerant pressure sensor O-ring in your Audi is a small but vital seal that ensures refrigerant does not leak where the pressure sensor meets the A/C line. This O-ring maintains pressure integrity and prevents refrigerant loss, which is critical to the function of the entire air conditioning system. Replacing worn or damaged O-rings helps restore A/C system efficiency and prevent major repairs.
Even a minor leak at the pressure sensor can reduce cooling performance and trigger HVAC fault codes. A proper seal helps maintain the correct system pressure and supports accurate sensor readings. Replacing the O-ring during sensor service or anytime the system is opened helps ensure long-term reliability and optimal cooling function.
These O-rings are made from high-temperature and chemical-resistant rubber compounds designed for automotive A/C systems. Their size and composition are matched exactly to Audi’s factory specifications.
